ISOLATION AND PARTIAL CHARACTERIZATION OF CATECHOL-TYPE SIDEROPHORE FROM PSEUDOMONAS-STUTZERI RC-7

Pseudomonas stutzeri RC 7 grown under iron-deficient conditions produced catecholtype siderophore, which was identified to be arginine conjugate of 2,3-dihydroxy-benzoic acid. Hydroxamic acids were not detected. The concentration of siderophore in the culture supernatant was maximal after 24 h of growth. Addition of iron to the medium increased bacterial growth but repressed the production of siderophore. © 1990 Springer-Verlag New York Inc.
